solar fuses

Seems like if something happens in the confines of a trailer a fuse isn’t going to help much, the battery or controller will still be pumping juice through the line up to the fuse block most likely melting wire and starting a fire. On my trailer near as I can tell the main lines off the battery to the converter are not fused.

Doesn't work that way. DC requires a circuit. Think of a circle. If you break the circle (circuit), nothing happens. A popped fuse stops current (amps) flow.
